3) A mass of 5 kg is resting on a horizontal, frictionless surface. Force 1 is applied to it at 20 degrees below the horizontal in the -x direction, force 2 has a magnitude of 88 N and is applied in the +x direction , and force 3 has a magnitude of 25 N and is applied vertically downwards. When these forces are applied, the normal force acting on the mass is twice the amount of its weight. Also, when...
A mass of 3kg is resting on a horizontal frictionless surface. Force 1 is applied to it at 59 degrees above the horizontal, force 2 has a magnitude of 33N and is applied vertically upwards, force 3 has a magnitude of 10N and is applied vertically downwards and force 4 has a magnitude of 57N and is applied in the negative x direction to the object. If the amount of force 1 is such that the mass just begins to...
A mass of 12 kg is resting on a horizontal surface without friction. A force of 107 Newtons is applied in the +x direction, a force of 13 Newtons is applied in the -x direction, and a force of 11 Newtons is applied in the -y direction (downward). What is the acceleration of the mass in m/s2? If in the -x direction, include a negative sign.
A mass of 4 kg is placed on a horizontal surface with a coefficient of kinetic friction of 0.29. A force is applied vertically downward to it and another force of 88 Newtons is applied at 11 degrees below the horizontal. As it moves 9 meters in the +x direction it loses 194 Joules of kinetic energy. What is the amount of the force which is applied downward in Newtons? * the answers is 316.17, but how do you get...
An object with a mass of 5 kg lies is on a horizontal surface with a coefficient of kinetic friction of 0.75. A force of 30 Nis applied to it DOWNWARDS, perpendicular to the surface, a force of 40 N is applied to it at an angle of 30 degrees above the +x axis, and a force of 20 N is applied to it in the negative x direction. The mass moves 10 m in the positive x direction with...

) A mass of 6 kg is resting on a horizontal with friction with a coefficient of static friction of 0.71 and coefficient of kinetic friction of 0.30. A force of 9 N is applied vertically upwards to the mass, and a force of 15 N is applied vertically downwards to the mass. What is the maximum static frictional force for this situation in Newtons?
A mass of 7 kg rests on a floor with friction. One force is applied vertically downward of 23 Newtons and another force is applied in the +x direction such that it just begins to move the mass. The force of 23 Newtons is then applied vertically upwards instead of downwards and another force is applied in the +x direction which just begins to move the mass that force is 141 Newtons less than the first case. What is the...
Problem 5: A block with a mass of m=37 kg rests on a frictionless surface and is subject to two forces acting on it. The first force is directed in the negative x-direction with a magnitude of F1=8.5 N. The second has a magnitude of F2 = 19.25 N and acts on the body at an angle θ = 17° measured from horizontal, as shown.Part (a) Please use the interactive area below to draw the Free Body Diagram for this...
(14.2) A block of mass m = 10 kg riding on a frictionless horizontal plane is subjected to five forces. The weight of the block and the normal force of contact with the plane both act in the vertical direction, cancel, and may be henceforth ignored. Three applied forces, →F1 , →F2 , →F3 , act horizontally on the block. The information that we have been able to gather about the applied forces is summarised as follows: F1 = 10...
